Overview

Now you can increase your everyday productivity by gaining powerful and convenient access to your external hard drives, printers, mobile devices and other peripherals.

Reliable performance even in tough industrial environments

Designed for performance and durability, the industrial-grade hub features a rugged, metal housing. Its wide-range 7-48V DC terminal block input gives you the flexibility to power the hub as required, based on your own power input capabilities. Plus, it supports an extended operating temperature range (0°C to 70°C), helping to ensure reliable performance even in the most demanding factory and industrial environments.

The rugged hub also offers ESD protection to each USB port, which can help safeguard your investments by preventing damage to your connected devices.

Secure and versatile installation on DIN rails or surfaces

This wall-mountable USB 3.0 hub can be securely mounted to surfaces, under desks, and in other high traffic areas where there is a concern that USB connections may become unplugged. Plus, it also includes optional DIN rail mounts for use with equipment rack installations.

Frequently Asked Questions

Before You Buy

It is possible to use some USB hubs without a power supply, however, doing so may prevent the USB hub or certain high-power USB peripherals from operating. It is always recommended to use an included power supply with a USB hub when possible.

When a power adapter is not used on a hub that comes with a power adapter, power is drawn from the USB port on the computer and then divided between the ports on the hub. This reduces the power delivery to individual ports and high-powered USB peripherals, such as external hard drives, may not start.

On USB hubs that can use a power adapter, more power can be supplied to USB ports than what is possible with a single USB port.

If your USB peripherals require power adapters, they probably do not require power from the USB port and can be used on a USB hub without a power adapter. With USB peripherals that use power adapters, the USB ports on the hub are only used for data transfer and do not draw power from the hub.

USB peripherals that require low power (for example, keyboards and mice) can be used on hubs without a power adapter, in conjunction with other low-power USB peripherals. In this case, power is drawn from the computer's USB port, as described above.

Troubleshooting

Industrial USB hubs offered by StarTech.com require an external power supply that connects to the terminal block on the hub. StarTech.com does not sell power supplies for these hubs and a power supply must be provisioned separately.

To select a power supply, you need to determine the maximum power requirements (wattage) of the hub.

The equation you should use to determine the power requirements is P = 5 * I * N, where the following is true:

P is the power in watts.

5 is the voltage of the USB port.

I is the current of the USB port in Amps.

I = 0.5 A for USB 2.0.

I = 0.9 A for USB 3.0.

N is the number of USB ports.

For example, a four-port USB 3.0 hub's maximum power requirement is P = 5 * 0.9 * 4. Therefore, the minimum wattage of the power supply for the four-port USB 3.0 hub is 18 watts.

When you determine the power requirements of the hub, you can choose a power supply. The following criteria must be met when you select the power supply:

The voltage must be within 7 to 24 or 7 to 40 Volts DC, depending on the specifications of the USB hub.

The power supply must convert AC to DC (no AC output).

The power rating is equal or greater to the requirements of the hub.

Most power supplies come with a rating in volts (V) and amps (A). To determine the current in amps, use I = P / V, where the following is true:

I is the current of the power supply.

P is the calculated power of the hub.

V is the chosen voltage of the power supply (between 7 to 24 or 7 to 40 volts).

For example, if a hub requires 18 W and you choose a 12 V power supply, the current of the power supply would be I = 18/12, I = 1.5A.

Power supplies are sold by a number of online distributors and resellers. StarTech.com does not provide any official recommendations for distributors or resellers.

When you troubleshoot issues with a USB hub, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

USB A-to-B cable

Computer USB port

USB peripheral(s)

To test your setup components, try the following:

Use the USB cable and USB peripheral(s) in another setup to see if the problem is with the components or the setup.

Use a different USB cable, USB port, and USB peripheral in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

Test each cable individually.

Use short cables when you are testing.

When you test the hub, make sure that you do the following:

If a power adapter is included, provide power to the USB hub.

Attach a USB peripheral. The USB hub will not appear in any hardware listings on your system, but USB devices do appear when they are connected.

Install the drivers for the USB peripheral.

Install the latest drivers for the USB controller and motherboard chipset.

Note: No drivers or software are required for the USB hub to work with your operating system. The USB hub works independently of software and works with any operating system.

When testing your USB peripherals, make sure that you do the following:

If required, attach external power.

Confirm that the peripheral works on a standard USB port.

If the USB peripheral(s) can be detected on a standard USB port and not on the hub, do the following:

Use a new USB A-to-B cable.

Test your setup using basic USB peripherals, such as a keyboard or mouse.
